LeafletJS with Google Tag Manager and more geoJSON points

In this tutorial I introducing: Leaflet supports all of the GeoJSON types above, but Features and FeatureCollections work best as they allow you to describe features with a set of properties. We can even use these properties to style our Leaflet vectors. onEachFeature: A Function that will be called once for each created Feature, after it has been created and styled. Useful for attaching events and popups to features. pointToLayer: A Function defining how GeoJSON points spawn Leaflet layers. It is internally called when data is added, passing the GeoJSON point feature and its LatLng.
